MTN - PLEASE PAY BACK MY MONEY URGENTLY

MTN is the worst when it comes to customer service. Will never make use of their services into the future. I have paid up my account on 27 December 2021 and cancelled my data account at the MTN store in Kimberley. Boom on 03 January 2022 MTN deducted R1100 from my account. MTN - PLEASE PAY BACK MY MONEY URGENTLY.
